Effect of different number of ECAP passes on creep in Cu-Zr alloy
Original language description
A coarse-grained binary Cu-0.2wt%Zr alloy was processed by equal-channel angular pressing (ECAP) in order to evaluate the effect of severe plastic deformation on the thermal stability of resulting ultrafine-grained microstructure after ECAP and on creepbehaviour of the pressed alloy. Constant stress creep tests in tension were conducted at temperature 673 K and at the different applied stresses. It was found that the Cu-0.2Zr alloy after the first four ECAP passes exhibited higher creep resistance by comparison with unpressed state. However, the alloy processed by 8 ECAP passes showed faster creep rate than unpressed material under the same loading conditions. The measured value of stress exponent of the creep rate n6 indicates possibility of an intragranular deformation mechanism as the rate-controlling process in creep of an alloy after 8 ECAP passes. Furthermore, creep behaviour of ECAPed material may be influenced by mesoscopic boundary sliding along shear bands.
